Last month we blogged about a bug marring Flash playback on the latest 27-inch Apple iMacs. Users on several Web sites, including the Apple Discussion Threads, noticed a problem with the Flash player that caused choppy audio and video playback, but it appears that the newest Mac OS X v10.6.2 update fixes the issue that was apparently caused by a conflict with the Airport driver.

According to Apple, the update "addresses video playback and performance issues for iMac (21.5-inch, late 2009) and iMac (27-inch, late 2009) computers that may occur in some situations while AirPort is turned on." Since our own 27-inch iMac also experienced slow Flash streaming and intermittent sound hiccups with the AirPort turned on, we downloaded the 10.6.2 update and left it to sleep overnight.

Prior to the update, the Flash Player consumed 114.4 percent of system resources, but 24 hours after the update we're happy to report 26.8 percent usage in the activity monitor and smooth performance across all popular streaming video Web sites like YouTube, Hulu, etc.

Much thanks to the Apple Forums and Apple itself for quickly addressing the needs of its community. If you haven't updated yet, simply choose Software Update from the Apple menu to install OS X v10.6.2.

After reading Engadget's report citing recent complaints about Flash video playback mucking up system resources on the latest 27-inch Apple iMacs, we decided to test out the claims using our own system. Users on the Apple Discussion threads noticed a bug in the Flash Player that bogs down CPU processes, resulting in choppy audio and video playback.

We visited several sites with heavy streaming video content like Hulu, YouTube, and the Break Media Network, and experienced similar issues: popping sounds and jerky video rendering the content unwatchable on several accounts. Like many of the users in the Apple thread, we called up the Activity Monitor and saw that the Flash Player demanded a surprising 114.4 percent of the iMac's CPU processes.

We were able to temporarily fix the problem by putting the computer to sleep and waking it up, but some people are speculating that a hardware malfunction could be to blame. We've also tried to contact Apple for official word, but our messages have been as yet unreturned.

If you're experiencing similar problems, we'd like to hear about it--leave a comment and let us know the issue and what you did to fix it.

Sure, you can probably score a better price buying audio gear online, and it's certainly easier, but is it a smart way to go? I don't think so.

First, buying hi-fi without listening to it is a bad idea. Smart buyers compare one product to another, it's simply the best way to learn what your choices are. Granted, it's not the same as hearing speakers in your own room, but at least you're hearing them in comparison to each other under the same conditions.

Online reviews, including the ones I write for CNET and print magazines offer my opinions about sound. But reviews by me or anyone else can't predict about how, say a speaker, works with a receiver that's similar to yours. I have no idea about your specific needs, your room size, acoustics, taste in music, etc.

Use my reviews as a starting point and then try and listen for yourself.

User reviews? Hey, I make my living writing audio reviews and my opinions are drawn from my experiences with literally thousands of audio products. I can point you in the right direction, but at the end of the day, its your ears and your money. Buy what you like; just make sure you've heard it.

A good salesperson can offer sound advice based on your specific needs. That's a huge advantage online sales outlets can't duplicate. Yes, finding the right store or salesperson can take time, but that's true for doctors, lawyers, plumbers, and contractors, but once you've found a good one, their advice and council can be a huge asset. If you're spending $500 or more for speakers or a receiver try to make the effort to hear the thing. A successful salesperson has lots of happy customers, there's no other way to be successful. I sold audio for 16 years, I know from where I speak.

The cracked Kindle 2 that's at the center of the lawsuit.

Here's quick update to the story we posted the other day on a couple filing a class-action lawsuit over a potential design flaw in Amazon's Kindle 2 involving the company's cover and cracks developing around the clasps where the cover attaches to the device.

Amazon has decided that it will now replace Kindles that have been cracked by the cover free of charge, reversing its earlier stance that the Kindle 2's warranty didn't cover such cracks and required a $200 fee to repair. As expected, Amazon wouldn't comment on the lawsuit itself, which will apparently continue for the time being.

The couple's lawyer, Beth Terrell, told the Seattle Times that the lawsuit would proceed: "If they [Amazon] would like to resolve the matter, I think the way to do it is through a court-approved process."

We'll see how the settlement plays out, but I think the plaintiff is looking at free Kindles for life and lot of free e-books.

So we've started our back-to-school retail roundup of laptops, and while Dan and Scott got their first reviews posted without incident (the HP Pavilion dv7-2185DX and Sony Vaio FW480J/T, respectively), I wasn't as lucky with the Asus G71GX-RX05.

Actually, that's not entirely true. You see, the review was sailing right along until I started reading complaints about the system's Nvidia GeForce GTX 260M graphics adapter basically dropping frame rates to 1-2fps once the GPU temp hits roughly 81 degrees Celsius. So we did a little more testing and, sure enough, the frame rates dropped and we couldn't get them back up without a restart.

Turns out Asus is aware of the problem and has been busily working on a fix. Some hiccup in the BIOS is causing the drop out, and the manufacturer will be issuing a new BIOS version on or about July 9.

As soon as we have a chance to test it out, we'll be revising and rating our review. However, if you've already bought one, rest assured that a fix from Asus is on the way and your frame rates will be back where they belong. (Which, at least in our tests, was very good for the well-configured $1,149 laptop.)

Update: The new BIOS is ready for download. For the easiest updating, use the Asus Live Update app preinstalled on the laptop. It will download the new BIOS and then just follow the onscreen prompt to flash your system.

You can also go to the Asus support site and look up the model number and download the BIOS. Installation instructions are available from there as well.

We'll be testing out the new BIOS today and with any luck refreshing our review with performance results and ratings.

Canon on Wednesday released new firmware for its EOS 5D Mark II camera that the company said "improves and mitigates" the "black dot" problem that marred some images from the high-profile, high-end SLR.

Version 1.0.7 of the 5D Mark II firmware software is downloadable from Canon's Web site. (I encountered some dead ends on the site, but eventually found the 9MB download on the U.S. site at this address.)

I've just run some tests. My preliminary opinion is that there's grounds for optimism that the firmware indeed seems to have taken care of the problem. See the shots below taken at ISO 800 and 3,200, magnified to three times regular size.

Updated 9:27 and 9:45 a.m. PST with further details from Canon USA announcement.

Canon has acknowledged the "black dot" problem that mars some shots taken with its new 5D Mark II camera and is preparing "correction firmware" designed to deal with the problem, the company said.

"We are currently investigating ways to improve and/or mitigate these phenomena. An announcement will be made on the Canon Web site when measures to address these phenomena have been decided," according to a statement dated December 17 that appeared on Canon's Australian support and service Web site.

A later Canon USA service announcement was largely identical, but also said Canon is "examining measures to reduce or eliminate these phenomena by providing correction firmware."

Firmware fixes can be downloaded and installed, a much cheaper and easier process than the physical repairs the company undertook to help with Canon 1D Mark III autofocus problem.

Canon described the problem the same way many who've complained about it have: "When shooting night scenes, the right side of point light sources (such as lights from building windows) may become black. The phenomenon may become visible if the images are enlarged to 100 percent or above on a monitor or if large prints of the images are made." For some examples, check farther down this post.

The company also said it's looking into vertical banding noise that can show when shooting files in the sRAW1 mode, which produces a smaller file size than regular raw images.... Read more

Some photographers have been frustrated with Canon's silence on the "black dot" issue that's afflicting its new EOS 5D Mark II camera, but the company plans to speak soon.

"Watch for an official Canon comment on this issue in the very near future," said Canon USA technical adviser Chuck Westfall in a Wednesday response to a question posted on his monthly question-and-answer column at The Digital Journalist.

The black spots appear to the right of very bright spots in some occasions, and many are wondering whether the issue is an unavoidable consequence of the sensor or something that can be altered with the camera's more mutable firmware.

Judging by Canon's earlier statements about issues such as the EOS-1D Mark III autofocus saga, though, it wouldn't be wise to count on a terribly revealing statement. This could well be at the stage of just acknowledging the issue still.

The Canon 5D Mark II is the new fourth-place member of DxO Labs' test of image sensor scores.

One verdict is in on Canon's EOS 5D Mark II: its sensor ranks very high on DxO Labs' test of sensor performance.

The black-spot issue notwithstanding, Canon's new full-frame SLR came in at fourth place with a score of 79.0, bumping Sony's 78.9-scoring Alpha A900 down a peg but still trailing Canon's top-end EOS-1Ds Mark III at 80.3. Nikon's D700, the closest rival to the 5D Mark II, is a notch ahead at 80.5.

More relevant for the potential upgrade market, new Canon SLR's score is significantly better from that of its predecessor, the 5D, whose score is 70.9. On a pixel-by-pixel basis, the 12.8-megapixel 5D's sensor actually has a lower signal-to-noise ratio, but when measured over an entire 8x10 print, the 5D Mark II's higher 21.1-megapixel resolution wins on that measurement.

The DxOMark Sensor test measures how well a camera's sensor fares when it comes to dynamic range, color depth, and low-light performance. The test doesn't measure any number of other camera issues such as autofocus, value, or image processing. But it's still useful given DxO Labs' engineering rigor and the central role a sensor plays in the abilities of a camera.

Pixel-peepers have been devouring DxO's new statistics; the curious can try this link to a comparison of the 5D Mark II, Nikon D700, and Sony A900. However, it should be noted, DxO Labs considers that scores must be at least of 5 points apart to be significant.

There's been much discussion about whether the $2,700 5D Mark II performs better than the $6,500 1Ds Mark III, which has the same resolution. The DxOMark tests give the edge to the top-end model based on its better color and dynamic range--the ability to capture both bright and dark regions--but the 5D Mark II wins out in low-light performance. Digging deeper into the charts, though, the 5D Mark II fares better in dynamic range at higher ISOs.

All these cameras perform better than the common herd by virtue of full-frame sensors measuring 36x24mm, the size of a full frame of 35mm film. Most digital SLRs have a smaller sensor that can't capture as much information overall, but those models are vastly more affordable.
